I noticed that underneath my house there is no insulation. In researching about insulation I learned that the traditional pink insulation absorbs water, can mildew and gets thin over time. Plus it needs space around it to allow it to breathe so it wont collect moisture which results in gaps or leaks of temperatures around the house. This didn’t sound too good to me and then I discovered the Polyurethane Spray Foam Kit at sprayfoamdirect.com It sprays on like paint and then expands to ” with an R value of so it seems simple to use, much cheaper than the regular pink insulation and it fully covers all the surface with no gaps and doesnt absorb moisture. I just want confirmation that this stuff really works as it says. Can someone back this up? Thanks!

I would use it if I could afford to. Not only do you get the r-value, but it makes your floor air-tight. I think that the air draft stoppage is as important as the insulating factor
I have never personally applied foam insulation but I have seen it a few work sites and had it installed in my second floor addition. I cannot recommend it enough, we added another story to our house and there was no increase in our heating gas usage. I won’t say we are paying the same as the rates have risen. The fact that it completely seals the area from any air infiltration makes it worth the money. The installers wear respirators, not just a dust mask, and those tyvek suits that look like bio-hazard outfits that you may have seen in a movie. Any over spray will stick to whatever it touches so take precaution.
